Miniaturized refrigeration equipment heat exchanger copper pipe insertion guide structure

The copper tube insertion guide, designed with a segmented variable cross-section guiding structure and an attitude adjustment groove, solves the problems of fin misalignment and skewness during copper tube insertion in miniaturized refrigeration equipment. This improves insertion accuracy and efficiency, enhances the bonding strength between the copper tube and the fins, improves heat exchange performance, and reduces costs.

Abstract

The application discloses a small-sized refrigeration equipment heat exchanger copper pipe inserting pipe guiding structure and relates to the field of air conditioner condenser processing equipment.The heat exchanger is provided with fins, and the fins are provided with inserting holes.The guiding piece comprises a connecting rod and a segmented variable cross-section guiding part connected to the front end of the connecting rod;an attitude adjusting groove is circumferentially arranged on the outer periphery of the segmented variable cross-section guiding part;when the guiding piece is axially inserted into the inserting holes of the fins, the segmented variable cross-section guiding part keeps a rigid state to provide correct positioning for the fins;and the front end of the copper pipe is inserted into the segmented variable cross-section guiding part.The structure design of the segmented variable cross-section guiding part and the attitude adjusting groove can keep a high rigid state through oil filling when the guiding piece is initially inserted into the fins, can forcibly support and correct the deviated fin holes through the large outer diameter of the flat part, and can eliminate the hole position deviation caused by accumulated tolerances.
